    Aster species as one of the traditional Tibetan medicinal materials in China, have high medicinal and unique ornamental value, the market demand has been gradually increasing. In this study, seven species of Aster were selected from Tibetan, and the Maxent model was used to investigate the potential distribution of them in China and the changes of their suitable habitat under future climate conditions based on the actual survey and distribution data of specimens on the site and 6-8 environmental variables. The results showed that temperature and precipitation were important limiting factors affecting the distribution of Aster, and bio2, bio3, and bio10 were common environmental influencing factors of Aster species. Under the current climate, The mainly potential distributed region of the seven Aster species in the Qinghai-Tibet Plateau. Under different climate conditions in the future, the suitable area of A. diplostephioides and A. asteroides will shrink significantly, while the suitable area of A. yunnanensis var. labrangensis, A. farreri, A. souliei, A. poliothamnus and A. tongolensis will expand.Environmental factors provide a large gain in predicting the distribution of Aster species. Among the environments variables, isothermality (Bio 3) induced the largest impact on SDM and contains the most useful information for A. yunnanensis var. labrangensis (41.9%), A. diplostephioides (55.9%), A. souliei (41.5%) and A. tongolensis (20.2%), while A. asteroides (66.3%) and A. poliothamnus (26.8%) were more significantly affected by the mean temperature of warmest quarter (Bio 10), A. farreri (21%) was more significantly affected by the mean temperature of driest quarter (Bio 9). The study findings suggest that the distribution range of 7 species of Aster will be greatly impacted by climate change.This research helps identify the limiting factors affecting the natural distribution and potential suitable areas for Aster species, which can inform conservation efforts, plant introduction, acclimatization, domestication, and cultivation of Aster.
